Abstract: Inner round-tube evaporator is commonly used in horizontal direct cooling freezers, and evaporator is in line contact with the inner. The flat-tube evaporator is in surface contact with the inner, which effectively increases the heat exchange area. It is found that the product energy consumption can be reduced by 8.5% when the flat-tube evaporator is used instead of the round-tube evaporator.
